"You look at the type of players like Higuain we are trying to bring in and you have got to be encouraged," added Wilshere.

"I think we need a few more, not to step right into the team, but to add to the squad. We need our squad to be as deep as United's and [Manchester] City's. They can change their back four completely and still win. There is no way United would have won the Premier League trophy with 18 players.

"It is no secret we need to win a trophy. How long has it been now, seven or eight years? The players feel the pressure and we have gotten close a few times like with the Carling Cup a couple of years ago. I think once we win one, others will follow."
